About the Airtac SAI100 Standard Air Cylinder SAI100BX55
The AirTAC SAI100X55 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty handling. It provides a robust push force of 3927 N and a pull force of 3681 N at 0.5 MPa. The 55 mm stroke is optimal for short-stroke clamping, pressing, and heavy lifting tasks.
This specific configuration features a SUS304 stainless steel piston rod (material code B) for superior corrosion resistance. It utilizes PT tapered port threads and lacks a magnet. For high-temperature environments up to 70 C, the standard TPU seals can be swapped for Viton (code H).

Where the Airtac SAI100 Standard Air Cylinder SAI100BX55 Is Used
Heavy-Duty Pressing
Generates 5497 N of thrust at 0.7 MPa for securely seating bearings and bushings in automated assembly lines.
Robotic Gripping
Provides the high pulling force required to actuate large-scale mechanical grippers handling heavy castings.
Pallet Stopping
Short 55 mm stroke delivers abrupt, powerful stops for heavy pallets on converging roller conveyors.
Is the Airtac SAI100 Standard Air Cylinder SAI100BX55 the Right Cylinder?
Select this 100 mm bore when a 80 mm bore (2513 N push at 0.5 MPa) lacks the necessary thrust. The 55 mm stroke provides compact actuation. Because this is a non-magnet variant, position sensing requires external limit switches.
As a true ISO 15552 profile cylinder, it serves as a drop-in replacement for any standard 100 mm bore cylinder with a G1/2 port. If your mechanism must hold a load vertically without constant air pressure, select the SAIL locking variant or use an external pilot-operated check valve, as standard air cushions only decelerate the piston at stroke end.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAI100 Standard Air Cylinder SAI100BX55 FAQ
At 0.5 MPa, the push force is 3927 N and the pull force is 3681 N. At 0.7 MPa, the push force increases to 5497 N.
Yes, the SAI100X55 is dimensionally interchangeable per ISO 15552. It shares the same 100 mm bore, G1/2 port, and mounting interface as other standard profile cylinders.
